question
grammar
what does ことに...ことに... mean here?


The Google phrase you looked up is exactly what is happening here. It sounds
like トットちゃん is trying to escape the classroom.

This ことに attaches to some i-adjectives and na-adjectives and effectively adds
the English suffix 'ly'.

In this case we have 幸福なことに = "happily" and 不幸なことに = "unhappily".

> This classroom window, happily for Totto and unhappily for the teacher, was
> on the first floor and looked out onto the street.
